Answer #1

6.n=2

Possible values of l=0,1

0 =s ORBITAL

1=p orbital

No d orbital present.

Ans option A(statement I is incorrect)

7.N2O

Oxidation number of oxygen=-2

Let, oxidation number of N=X

2X-2=0

X=2/2=1

N2F4

Oxidation number of F=-1

Let Oxidation number of B=Y

2Y-4=0

Y=4/2=2

ANS  OPTION C
